活性氧化铝：一种高度多孔的氧化铝材料，通常用于吸附剂、催化剂和干燥剂等应用。
activated alumina //
名词 a granular highly porous and adsorptive form of aluminium oxide, used for drying gases and as an oil-filtering material and catalyst 活性氧化铝
Activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 square metres/g. The compound is used as a desiccant (to keep things dry by absorbing water from the air) and as a filter of fluoride, arsenic and selenium in drinking water.
